KPX091-C 25.4 mm Dia. x 88.3 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm

The KPX091-C is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a base shape of a circle, is designed for use in the visible light spectrum, specifically at a wavelength of 589 nm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.

The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is 4.803 mm, and the effective focal length (EFL) is 88.3 mm. The radius of curvature (R1) is 45.633 mm, and the back focal length (BFL) is 85.13 mm. The lens does not have an inner radius.

The KPX091-C is coated with MgF2, a common anti-reflective coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission in the spectral range of 400-700 nm. The lens's shape is spherical, which is the most common and simplest type of lens.

The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.newport.com/f/mgf2-n-bk7-plano-convex-lenses.
